Hunger — Patricia Williams

Five years have passed since the first wave of Dead ones-those that walk among the living, hungering for flesh. Now, The Patrol provides for the people in The Areas, as long as stringent rules are followed. After a close encounter with a Dead one, sixteen year old Claire Roberts begins to question everything she's been taught about The Patrol, the Dead ones, and her place in the world.
Hunger: The Dead Novelettes No. 1 is the first in a five book novelette series.  The second installment, Hunted: The Dead Novelettes No. 2 is now available on Amazon.
